摘　　要：采用干切削加工是修复环网柜接线套管表面烧蚀、裂痕的一种有效方法。利用单因素试验研究切削用量在未涂层、TiAlCrN涂层和TiAlSiN涂层刀具下对切削力的影响规律。在单因素试验的基础上运用Box-Behnken中心组合试验方法,采用性能最优的TiAlSiN涂层刀具对环网柜接线套管切削工作参数进行试验研究,以切削速度、进给量和背吃刀量为试验因素,以刀具切向力、轴向力、径向力为试验指标进行三因素三水平二次旋转回归正交试验。通过建立响应面数学模型,分析各切削工艺参数对切削性能的影响,并对试验因素进行综合优化。试验结果表明:影响切削力显著顺序为背吃刀量>进给量>切削速度;最优参数组合为切削速度94.589 m/min、进给量0.097 mm/r、背吃刀量0.501 mm,此时刀具切向力为11.75 N、轴向力为34.80 N、径向力为19.53 N;验证试验结果与理论优化值基本吻合。Dry cutting is an effective way to repair ablations and cracks on the surface of ring network cabinet bushing.A single-factor test was used to investigate the effect of cutting parameters on cutting forces under uncoated,TiAlCrN-coated and TiAlSiN-coated tools.Based on the single-factor test,the Box-Behnken central combination test method was applied to conduct an experimental study on the cutting working parameters of ring network cabinet bushing using the TiAlSiN-coated tool with optimal performance.A three-factor and three-level quadratic rotational regression orthogonal test was conducted with cutting speed,feed and back cutting as the test factors and tool tangential force,axial force and radial force as the test indexes.By establishing the response surface mathematical model,the influences of each cutting process parameter on the cutting performance were analyzed,and the test factors were comprehensively optimized.The test results show that the significant order of cutting force is back cutting>feed>cutting speed.The optimal combination of parameters is cutting speed 94.589 m/min,feed 0.097 mm/r,back cutting 0.501 mm,and the tool tangential force is 11.75 N,axial force is 34.80 N,radial force is 19.53 N.The results of the validation test generally agree with the theoretical optimization values.
